As I was fooling around the underside of my Superformance Cobra today I noticed a hole in the battery box. The hole is located at the rear, inside, bottom corner of the box. The box is located behind the left tire with normal access through the trunk. I was going to just patch the hole, but I thought maybe there is a reason there is a hole there and I should ask someone smarter than me. The battery box is made out of fiberglass. Any suggestions what to plug it with? It is less than 1/8" in diameter.
